Danny DeVito and Rhea Perlman have separated, leaving behind one of the longest marriages in Hollywood history.

The divorce papers have yet to be filed and there has been little to be seen of both DeVito and Perlman.

However, DeVito made his first public appearance since the announcement of their separation was made.

According to TMZ, the diminutive star of "It's Always Sunny in Philadelphia" was spotted Saturday having lunch with friends in Malibu. When asked by TMZ's cameras how he was doing, DeVito smiled with thumbs up saying "everything's good."

The reason the longtime couple split was apparently centered around DeVito's wandering eye.

According to RadarOnline, Pelman had finally had enough of DeVito's flirtacious behavior with other women.

"He may not appear to be a ladies' man, but Danny certainly gets a lot of female attention," claimed a source for RadarOnline. "Danny can be quite the flirt and because of his powerful status in Hollywood, he's not ashamed to abuse his position and chat-up young, aspiring women looking to make it in the industry."

The source went on to say that, "After years of turning a blind eye to it, Rhea finally snapped."

Stan Rosenfeld, a representative for 68-year-old DeVito, told ABC News early this month that the actor and the 64-year old actress Perlman have ended their 30 year marriage.

"The break-up has been on the cards for a long time, probably over 10 years, because they haven't been happy for a long, long time," said RadarOnline's source.

Together the couple has two daughters and a son: Lucy, 29, Grace, 27, and Jacob, 24.

DeVito and Perlman had been seen as a strong couple in Hollywood since they first got together. The couple met in 1970 and moved in together after only two weeks. They've been married since January 1982.

Perlman is most famous for her role on the classic sitcom "Cheers." DeVito can currently be seen on FX's "It's Always Sunny in Philadelphia" Thursday nights at 8p.m.
